Post Florida Update, keyword discussion

[anush]

Florida update is old new now. People are worried more about the present fluctuations in the SERP's.

But since you asked. From what I have seen any kind of optimization that is unnecessary or irrelevant can cause harm. Such as, kw's in general tags, sidebars & related posts, putting as many as kw's in alt text of image, non-clear categories or bubble categories. These are the main ones. However many others are also seen.
